All science has uncertainty. Global challenges such as disaster risk, environmental degradation, and climate change illustrate that an effective dialogue between science and society requires clear communication of uncertainty. Responsible science communication conveys the challenges of managing uncertainty that is inherent in measurements, input data, and model outputs, facilitating the society to understand the contexts where uncertainty emerges and enabling active participation in discussions.

Uncertainty communication can play a major role across the risk management cycle, especially during decision-making, and should be tailored to the audience and the timing of delivery. Therefore, research on quantification and communication of uncertainties deepens our understanding of how to make scientific evidence more actionable for risk reduction.

This session invites presentations by individuals and teams on communicating scientific uncertainty, addressing topics such as:
1. Innovative and practical tools (e.g. from social or statistical research) for communicating uncertainty.
2. Visual, verbal and numerical approaches for communicating uncertainty.
3. Pitfalls, challenges and solutions to communicating uncertainty to different audiences (e.g. experts, policymakers, media, general public, first-responders).
4. Communicating uncertainty in risk and crisis situations (e.g., natural hazards, climate change, public health crises).

Examples of research fitting into the categories above include a) new, creative ways to visualize different aspects of uncertainty, b) new frameworks to communicate the level of confidence associated with research, c) testing the effectiveness of existing tools and frameworks, such as the categories of “confidence” used in expert reports (e.g., IPCC), or d) research addressing the challenges of communicating high-uncertainty high-impact events.

This session encourages you to share your work and join a community of practice to inform and advance the effective communication of uncertainty in earth and space science.
